Abstract海洋二号微波定标辐射计HY-2 Calibration Radiometer(HY-2CR)采用了高增益、低副瓣、高波束效率低损耗的天线子系统。三个频率共用一个偏馈抛物面,天线频率分别为18.7GHz、23.8GHz和37GHz。采用双隔膜正交模耦合器实现双极化信号提取,利用紧凑型圆锥波纹喇叭进一步降低天线结构尺寸和质量。测试结果显示天线完全达到了设计要求。
Other AbstractHY2 microwave calibration radiometer(HY2CR)use sub-antenna system with high gain,low noise,high beam efficiency,and low loss. Offset parabolic together with compact conical corrugated horns is utilized for reduction of the dimension and weight for the feeds. The orthomode transducer(OMT)with two septums is employed to meet the demand of the dual polarizations for all three frequencies,which are 18.7 GHz,23.8 GHz and 37 GHz. The experimental results verify the design of the antenna.
